Checking that the stripping is even and does not damage the core wire or braided strands. The stripping dimensions should be accurate.

3.Braiding treatment:

Verifying that the trimming is done correctly, ensuring evenness and avoiding any damage to the core wire during trimming.

4.Insulation stripping:

Check if the stripping is even; ensure the dimensions of the stripping are correct; verify that there is no damage to the core wire or copper strands during the stripping process; ensure the insulation does not detach during partial stripping.

5.Heat shrink tubing application:

Verify the dimensions and type of the heat shrink tubing are correct.

6.Preparing for soldering:

Check if the soldering iron temperature is correct; ensure the copper strands of the core wire are properly arranged, free from branching, bending, or twisting; after preparing for soldering, inspect for any issues such as excess copper, branching, uneven copper strands, or insulation damage caused by heat.

7.Soldering:

Verify the temperature of the soldering iron is correct; ensure the insulation is not damaged during soldering; the solder joint should be smooth, without any solder spikes; avoid cold soldering or poor soldering quality.

8.Terminal crimping:

In this step, check if the terminal wire meets the correct standards; inspect for any flaring, misalignment, or excessive or insufficient exposure of the core wire and insulation.

9.Terminal insertion:

Check the type of terminal and connector for correctness; examine the terminals for any signs of damage or deformation; ensure there are no incorrect or incomplete insertions of the terminals.

10.Wire harness crimping:

Verify the correct type of connector; ensure the wire harness is oriented correctly; inspect the core wire to ensure there is no exposed copper, damage, or insulation burns; verify proper crimping.

11.Heat shrink tubing heat treatment:

Ensure the heat shrink tubing has good shrinkage capability and does not cause insulation damage when heated.

12.Assembly of the housing:

In this step, inspect the housing for any misalignment, scratches, burrs, or other defects; check for any missing components or issues such as loose, discolored, or oxidized screws; ensure the assembly meets the required specifications; if the housing has a specific orientation, it must be assembled accordingly.

13.Labeling:

During the labeling process, verify the content of the labels to ensure correctness, clarity, and no missing characters.

14.Cable tie application:

When applying cable ties, check if the ties meet the required standards, correct orientation, and color.

15.Injection molding:

Check the cleanliness of the molds; inspect the molded parts for any bubbles, poor curing, poor adhesion, or material shortages.

16.Plug molding:

Inspect the molded areas of the plugs for any damage, burrs, material shortages, flow lines, foreign objects, or unevenness; ensure that the metal terminals are free from deformation, damage, exposed copper, or other defects.

17.Electrical inspection:

D-SUB Connector Introduction: What You Should Know About D-Sub Connectors!

7 月 12, 2023 通过 admin 0 评论 ,

The interface shape of D-SUB connectors resembles an uppercase “D,” which is why this type of connector is commonly referred to as D-SUB. These connectors are used for analog or digital interface signals and can be found in various applications in our daily lives, such as printer cables and monitor cables.

D-SUB connectors are available in different types, including DB solder-type, DBH plug-type, DML crimp-type, DMS straight-type, DMR right-angle board-mount type, DMRH right-angle board-mount type, 57S straight-type, 57BR right-angle board-mount type, DRB pin-type, HDC ultra-thin type. Additionally, there are DVI series, VGA series, DR series, HDR series, SCSI series, and high-current series connectors. Among these, the VGA series and DVI series are the most commonly used D-SUB connectors.

The connector housing of D-SUB connectors is available in five different sizes, and each housing size can have two different pin configurations. Standard housing sizes have 2 rows of pins, while high-density housing has 3 rows of pins.

D-SUB connectors are relatively large in size and can appear heavier compared to newer connectors. As a result, it can be challenging to connect and disconnect these connectors in tight spaces. However, right-angle adapters can rotate 90 degrees without damaging the connector, helping to effectively utilize D-SUB connectors in cramped spaces.

The pins inside the housing of D-SUB connectors are exposed, making them susceptible to bending or breaking. To prevent pin damage, it is recommended to use D-SUB plug or socket protective caps to safeguard the pins when not in use. Additionally, gender changers and socket savers can help reduce stress on the connectors caused by frequent plugging and unplugging.
